1 Chapter 1: Operation Chapter 1: Operation 1.1 Introduction Your ST40 Compass instrument: • Provides true and magnetic bearing information. • Enables a locked bearing to be defined either manually, or automatically by a course computer. In this mode, the instrument shows the deviations from the locked bearing and the direction to steer to achieve the locked bearing.

7 Chapter 2: Maintenance and Fault Finding Chapter 2: Maintenance and Fault Finding 2.1 Maintenance Servicing and safety • Raymarine equipment should be serviced only by authorised Raymarine service technicians. They will ensure that service procedures and replacement parts used will not affect performance. There are no user-serviceable parts in any Raymarine product. • Some products generate high voltages, so never handle the cables/ connectors when power is being supplied to the equipment.
8 ST40 Compass Instrument Owner’s Handbook Instrument Certain atmospheric conditions may cause a small amount of condensation to form on the instrument window. This will not harm the instrument and will clear after the instrument has been switched on for a short period. Periodically clean your ST40 instrument with a soft damp cloth. Do NOT use chemical or abrasive materials to clean the instrument.

11 Chapter 3: Installation Chapter 3: Installation This chapter describes how to install the ST40 Compass instrument, and associated Fluxgate Compass transducer. 3.1 Planning your installation Determine the best positions for both transducer and instrument, such that the EMC installation guidelines and the Site requirements (below) are satisfied. EMC installation guidelines All Raymarine equipment and accessories are designed to the best industry standards for use in the leisure marine environment.
12 ST40 Compass Instrument Owner’s Handbook • The equipment is supplied from a different battery from that used for engine start. Voltage drops below 10 V in the power supply to our products, and starter motor transients, can cause the equipment to reset. This will not damage the equipment, but may cause the loss of some information and may change the operating mode. • Raymarine specified cables are used at all times.
13 Chapter 3: Installation 57 mm (2.25 in) D4643-3 Note: If you intend fitting a nonstandard transducer, extra tools may be required. Site requirements Fluxgate Compass transducer The Fluxgate Compass transducer should be positioned as near as possible to the pitch/roll centre of the vessel, as shown in the shaded areas below. 0.3L to 0.5L L X 0.3L to 0.5L L Fluxgate Compass transducer siting 161_2c03.
14 ST40 Compass Instrument Owner’s Handbook The Fluxgate Compass transducer must also be sited: • At least 0.8 m (2 ft 6 in) away from the vessel's steering compass to avoid deviation in both compasses. • On a bulkhead below deck. Note: On steel vessels the Fluxgate Compass transducer can be mounted above deck. When mounted above deck, performance may be impaired due to increased motion. • To allow reasonable access for installation and servicing.
15 Chapter 3: Installation 3.2 Procedures Adapt these procedures as appropriate, to suit your individual requirement. CAUTION: Where it is necessary to cut holes (e.g. for cable routing and instrument mounting), ensure that these will not cause a hazard by weakening critical parts of the vessel’s structure. If in doubt, seek advice from a reputable boat builder.
16 ST40 Compass Instrument Owner’s Handbook 76 mm (3 in) 76 mm (3 in) D729-6 If you are not sure of the magnetic suitability of the chosen location, carry out a survey of the site as follows: 1. Temporarily fix a simple hand bearing compass at the intended location. 2. Swing the vessel through 360° while at the same time observing differences between the hand bearing compass and the vessel's main steering compass. 3.
17 Chapter 3: Installation Connections to the instrument You can connect your instrument: • Directly to the compass transducer as a stand-alone master instrument. When connected in this manner, the instrument must be connected to a suitable power source using the 1 m (3 ft) power cable provided. • As part of a SeaTalk system either as a repeater or, with a transducer also connected as a system master. To connect to SeaTalk, you will need an additional SeaTalk Interconnection Kit (Part No. E25028).
18 ST40 Compass Instrument Owner’s Handbook Stand-alone connections CAUTION Ensure that the power supply for each stand-alone ST40 instrument is protected by a 3 A fuse or circuit breaker. 3 A circuit breaker Red +ve Note: A 3 A fuse can be used in place of the circuit breaker, if preferred.

19 Chapter 3: Installation SeaTalk connections CAUTION When instruments are connected to SeaTalk, ensure that the power supply for the SeaTalk 12 V line is protected by a 5 A fuse or circuit breaker. Note: A 5 A fuse can be used in place of the circuit breaker, if preferred. 5 A circuit breaker Red (+ve) 12 V dc supply (e.g.

22 ST40 Compass Instrument Owner’s Handbook D4646-1 To bracket mount your ST40 instrument, do so in accordance with the Instruction Sheet, which is included with the Desktop Mounting Bracket. 3.3 Calibration requirement Once installation is complete and before you use your instrument, carry out the calibration procedures detailed in Chapter 4, Calibration. 161_2c03.
23 Chapter 4: Calibration Chapter 4: Calibration 4.1 Introduction The procedures in this Chapter must be carried out before the equipment is used operationally, to optimise the performance of the instrument with the vessel. Calibration information is presented in flow chart form. The flow charts show the various calibration screens and key presses necessary to carry out calibration. All key presses are momentary unless otherwise stated.
